No new fruit flies, but biosecurity staff have found larvae on two Auckland properties over the weekend.

It's now three weeks since the first Queensland fruit fly was found in a trap in Grey Lynn.

The total number of flies trapped stands at 14.

Ministry for Primary Industries staff have found larvae in fruit from trees on two properties, near where the first fly was discovered.

There are now four properties in the area being baited and sprayed, as the eradication process continues.
